◆ MCE_CALL_STATE_CHANGE_REQ

#define MCE_CALL_STATE_CHANGE_REQ "req_call_state_change"

Request call state change.

Since: mce 1.8.1

MCE tracks call state separately:

from ofono modem and call properties
for each client using issuing call state requests

The overall call state will be "ringing" if at least one of the tracked entities declares ringing state.

The call type will be "emergency" it at least one of the tracked entities declares emergency call type.

If a client that has requested a call state change drops from system bus, it will be handled as if the client would have made a "none":"normal" request.

Note: Aegis credential for Nokia N9: mce::CallStateControl

Parameters

call_state	string: call state to request, one of: MCE_CALL_STATE_NONE MCE_CALL_STATE_RINGING MCE_CALL_STATE_ACTIVE MCE_CALL_STATE_SERVICE

Since: mce 0.5

Note: Applications should never make explicit display on requests.

◆ MCE_DISPLAY_DIM_REQ

#define MCE_DISPLAY_DIM_REQ "req_display_state_dim"

Since: mce 1.6.20

Note: Applications should never make explicit display dim requests.

Since: mce 1.33.0

Blank screen via going through Display Low Power state.

If LPM feature is not enabled, blanks display immediately.

Low power mode is a display off sub state. From normal display state signaling point of view it behaves just as display off would. Depending on available hw support and configuration extra ipc relevant for home screen / system ui only might happen.

Note: Aegis credential for Nokia N9: mce::TKLockControl

Parameters

mode	string: requested tklock state, one of: MCE_TK_LOCKED MCE_TK_SILENT_LOCKED MCE_TK_LOCKED_DIM MCE_TK_LOCKED_DELAY MCE_TK_SILENT_LOCKED_DIM MCE_TK_UNLOCKED MCE_TK_SILENT_UNLOCKED

◆ MCE_PREVENT_BLANK_REQ

#define MCE_PREVENT_BLANK_REQ "req_display_blanking_pause"

Prevent display from blanking.

Since: mce 0.5

Normal blanking timers are stopped for 60 seconds - under roughly the following conditions:

Display is already on and lockscreen is not active
Display is already on, lockscreen is active but compositor has notified that user interaction is expected and the blanking prevent request originates from the same process that owns the topmost window on screen.

The exact details are subject to change and clients showld track MCE_PREVENT_BLANK_ALLOWED_SIG signals to know when making blank prevention calls are allowed/ignored (and query the initial state with MCE_PREVENT_BLANK_ALLOWED_GET).

To keep display from blanking for longer periods, the client needs to re-issue this call every 60 seconds.

When application no longer wishes to keep display from blanking, it should make a MCE_CANCEL_PREVENT_BLANK_REQ method call.

Note: If client drops from the system bus, or misses the 60 second renew period, it is handled as if the client would have made a MCE_CANCEL_PREVENT_BLANK_REQ method call.; Previously mce waited exactly 60 seconds for renew calls which meant clients had to use shorter than 60 second renew periods to avoid hiccups. Since mce >= 1.93.0 the hard limit is 65 seconds and thus clients can schedule renewing to occur once / 60 seconds.

◆ MCE_CANCEL_PREVENT_BLANK_REQ

#define MCE_CANCEL_PREVENT_BLANK_REQ "req_display_cancel_blanking_pause"

Cancel display blanking prevention.

Since: mce 1.10.35

3) repeat MCE_CPU_KEEPALIVE_START_REQ calls in interval that is shorter than the maximum obtained at (1)

4) call MCE_CPU_KEEPALIVE_STOP_REQ when finished

MCE keeps track of active clients and blocks late suspend until all clients have called MCE_CPU_KEEPALIVE_STOP_REQ, lost D-Bus connection (exit, crash, ...) or all timeouts have been missed.

Since: mce 1.23.7

An unique within process tracking id can be passed to all cpu keepalive related D-Bus method calls. This allows mce to keep track of multiple, possibly overlapping keepalive periods from one process.

Old code that does not pass the tracking id still works as long as the client process does not have multiple overlapping periods at once.

Parameters

context string: "unique enough" tracking id

Returns: int32: renew period in seconds

Since: mce 1.12.8

This method call must be repeated periodically to keep the system from entering late suspend.

The period length can be obtained via MCE_CPU_KEEPALIVE_PERIOD_REQ.

Note: The boolean reply message is optional and will be sent only if requested.

Parameters

context string: "unique enough" tracking id

Returns: boolean: TRUE on success, or FALSE in case of errors

#define MCE_FADER_OPACITY_SIG "fader_opacity_ind"

Signal for controlling compositor side display dimming.

Since: mce 1.34.0

In situations where there is not enough dynamic range available to make the difference between "on" and "dimmed" display states clear to user, mce sends this signal to instruct compositor to complement the display backlight brightness based dimming by blending the whole visible ui with an all black rectangle.

The amount of requested dimming depends on hw specific configuration and backlight brightness level in use.

The requested fade animation duration is derived from what mce would use for backlight brightness fade anination and depends on mce side configuration.

It is expected that compositor can and will cap both the amount of dimming and transition length to some span that makes sense from compositor point of view.

dimming	int32: dimming percent 0 for normal, undimmed ui ... 100 completely blacked out ui
duration	int32: fade animation duration [ms]
